Calgary Mortgage Guide · Updated June 2026
The complete guide to mortgages in Calgary, Alberta
Calgary's housing market sits in a sweet spot in 2026: detached benchmark prices hover near $650,000, condos near $340,000, and interprovincial migration from Ontario and BC continues to push demand. If you're buying, refinancing, or renewing a mortgage in Calgary, the math is meaningfully different from Toronto or Vancouver — Alberta has no provincial land transfer tax, lower legal fees, and Land Titles registration that rarely exceeds $400. That alone saves the average Calgary buyer $8,000–$15,000 at closing vs. an Ontario buyer.
Where Calgary buyers get tripped up is everything after the purchase price: CMHC mortgage insurance (required below 20% down, with premiums of 4.00% at 5% down, 3.10% at 10%, and 2.80% at 15%), the OSFI B-20 stress test (qualify at contract rate + 2% or 5.25%, whichever is higher), and Canadian semi-annual compounding which makes the effective rate slightly different from US-style monthly compounding. Every calculator on this site bakes those rules in by default, so the number you see is the number a Calgary mortgage broker would quote you.
Built by mortgage professionals and used daily by Calgary mortgage brokers, realtors, and first-time buyers, this site covers every scenario: monthly payments, what you can afford, Alberta closing costs, refinance break-even, rental property cash flow, and short-term rental ROI.
How this compares to RBC, TD, Scotiabank, CIBC & BMO calculators
Bank mortgage calculators are designed to sell you that bank's product. They omit CMHC mechanics, ignore Alberta-specific costs, and rarely show the stress test. Here's how our tool stacks up:
| Feature | Bank calcs | This site |
|---|---|---|
| CMHC premium auto-added at correct tier | Partial | Yes |
| Alberta land title fees (real formula) | No | Yes |
| OSFI stress test (qualify rate + 2%) | No | Yes |
| Accelerated biweekly vs monthly side-by-side | Rare | Yes |
| Refinance penalty: 3-month interest vs IRD | No | Yes |
| Investment property DSCR & cap rate | No | Yes |
| Airbnb / short-term rental ROI | No | Yes |
| Embeddable on broker / realtor websites | No | Yes |
| Lender-agnostic (no upsell) | No | Yes |
Calgary mortgage questions, answered
The questions Calgary buyers actually ask — with direct, numbers-first answers.
How much mortgage can I afford in Calgary?
Most Calgary buyers qualify for 4–4.5x their household income, capped by GDS ≤ 39% and TDS ≤ 44% under OSFI B-20. On a $120,000 household income with $50,000 down and no debts, you can typically afford a Calgary home around $520,000–$560,000 at today's stress-test rate. Use our Affordability Calculator for an exact number.
What is the minimum down payment for a house in Calgary, Alberta?
Canada-wide rules apply in Calgary: 5% on the first $500,000, 10% on the portion from $500,000–$1,500,000, and 20% on homes above $1.5M. CMHC insurance is required when you put less than 20% down and is added to your mortgage balance.
How is a Canadian mortgage payment calculated?
Canadian mortgages use semi-annual compounding (not monthly like the US), so the effective per-payment rate is slightly lower than nominal÷12. Our calculator applies the correct Canadian formula, then layers CMHC premium, your payment frequency (monthly, biweekly, accelerated), and amortization.
What are closing costs on a house in Calgary?
Budget 1.5–2.5% of the purchase price. Alberta has no provincial land transfer tax, but you'll pay Alberta Land Titles registration fees (~$50 + $2 per $5,000 of price; same formula on the mortgage), legal fees ($1,200–$1,800), title insurance ($300–$400), inspection ($400–$600), and PST on CMHC premium. See our Closing Cost Calculator for an itemized Alberta breakdown.
What is the mortgage stress test in 2026?
Under OSFI B-20, you must qualify at the greater of your contract rate + 2% or 5.25% — even if your actual payment is lower. This applies to all federally regulated lenders. Credit unions can choose their own qualifying rate.
Is it better to take a 25 or 30 year amortization in Calgary?
30-year amortization (available with 20%+ down on uninsured mortgages, and on insured first-time buyer new builds) lowers your monthly payment by ~$200–$350 on a $500K mortgage but adds ~$95K in lifetime interest at 5%. Use 30 years for cash-flow flexibility, then make accelerated payments.
How much does a $500,000 mortgage cost per month in Calgary?
At 4.99% on a 25-year amortization, monthly payment is approximately $2,909 for a $500,000 mortgage. With 5% down on a $526K home, CMHC pushes the financed amount higher; expect ~$3,045/month including insurance. Switch to accelerated biweekly to save ~$45,000 in interest.
Should I use a bank mortgage calculator or this one?
Bank calculators (RBC, TD, Scotiabank, CIBC, BMO) only show the bank's posted rate and miss CMHC premium impact, Alberta-specific fees, the stress test, and Canadian semi-annual compounding edge cases. This calculator is lender-agnostic and built specifically for Calgary/Alberta rules.
When should I refinance my Calgary mortgage?
Refinance when (rate savings × remaining months) > prepayment penalty + legal fees (~$1,500). On a fixed mortgage, the penalty is the greater of 3 months' interest or IRD (Interest Rate Differential) — often $8,000–$20,000. Run the math in our Should I Refinance? tool.
